Pull ARM SoC fixes from Arnd Bergmann:
 "This is a fairly large set of bug fixes on top of -rc1, as most of
  them were ready but didn't quite make it into the last-minute pull
  requests for the merge window.

  Allwinner:
   - fix for incorrect CPU overtemperature limit

  Amlogic:
   - multiple smaller DT bugfixes, and missing device nodes

  Marvell EBU:
   - add missing aliases for ethernet switch ports on espressobin board

  Marvell MMP:
   - DTC warning fix
   - bugfix for camera interface power-down

  NXP i.MX:
   - re-enable the GPIO driver on all defconfigs

  ST STM32MP1:
   - fix random crashes from incorrect voltage settings

  Synaptics Berlin:
   - enable the correct hardware timer driver

  Texas Instruments K2G:
   - fix a boot regression in the power domain code

  TEE drivers:
   - fix regression in TEE "login" method

  SCMI drivers:
   - multiple code fixes for corner cases in newly added code

  MAINTAINERS file:
   - move Kukjin Kim and Sangbeom Kim to credits (used to work on
     Samsung Exynos)
   - Masahiro Yamada is stepping down as Uniphier maintainer

  I did not include a series of patches that work around a regression
  caused by a bugfix in an ethernet phy driver that resulted in an
  inadvertent DT binding change. This is still under discussion"
